Abstract

The invention provides a driving source for a hydrogen thyratron control grid. The power of the driving source is supplied by a single-phase 220V power source. The driving source comprises a pulse transformer, wherein a pulse formation circuit is arranged at the primary level of the pulse transformer, and a negative bias generation circuit, a magnetic pulse compression circuit and an L-C low-pass matching circuit are arranged at the secondary level of the pulse transformer. According to the hydrogen thyratron control grid, the weight is reduced, the size is also reduced, and therefore integration of the driving source is facilitated; a hydrogen thyratron switch can be restrained from causing high frequency electromagnetic interference, connection of a hydrogen thyratron is avoided, the hydrogen thyratron is protected, and the service life of the hydrogen thyratron is prolonged; it can be ensured that the hydrogen thyratron works in an optimal state with low latency, low jitter, low drifting and high repetition frequency.

Description

technical field [0001] The invention relates to a hydrogen thyratron, in particular to a driving source for a hydrogen thyratron control grid. Background technique [0002] Hydrogen thyratrons feature low time jitter, low anode ignition delay time, low anode ignition delay time drift and high anode pulse current rise rate. It can be used in military, scientific research, medical fields and civilian high-tech products, including radar, laser, electron accelerator, and pulse modulator as a high-power switch with high pulse repetition frequency and fast rising edge pulse. [0003] The typical working circuit of a hydrogen thyratron is as follows: figure 1 shown, from figure 1 It can be seen from the figure that the hydrogen thyratron control grid needs dual power supplies: DC power supply B and DC power supply C. In addition to a positive trigger pulse to start the ignition, in order to shorten the capacitance elimination time and increase the repetition frequency of work, a ...
